The Hilt

Hilt - The upper portion of a sword consisting of the cross-guard, handle/grip, and pommel

Cross - The straight bar or "guard" of a sword, also called a "cross-guard". In Renaissance times, the name for both straight and curved cross-guards "the quillons". 

Grip - The handle of a sword, usually made of leather, wire, bone, wood, horn, or other material.  May be highly decorated.

Pommel: The counter-weight which secures the hilt to the blade, often a formidable crushing weapon itself.

Ricasso - The dull portion of a blade just above the hilt. It may or may not be decorated. Makers marks and other stamped symbols are typically found in this area.
